Abstract

resumo “lâmina e rotor de compressor e método para a montagem de um rotor de compressor” trata-se de lâminas de compressor construídas a partir de materiais compósitos. algumas lâminas de compressor exemplificativas podem incluir um painel de lâmina de compósito que inclui um aerofólio que tem uma envergadura que se estende radialmente para fora em relação a um eixo geométrico de rotação e/ou um dispositivo de fixação de lâmina radialmente para dentro do aerofólio em relação ao eixo geométrico de rotação. o dispositivo de fixação de lâmina pode ser circunferencialmente orientado em relação ao eixo geométrico de rotação. o dispositivo de fixação de lâmina pode ser disposto para engatar de modo liberável um dispositivo de fixação de bobina orientado geralmente de modo circunferencial. o dispositivo de fixação de bobina pode ser geralmente conformado como uma fenda do tipo cauda de andorinha circunferencial configurada para receber de modo deslizável o dispositivo de fixação de lâmina na mesma.Summary “compressor blade and rotor and method for assembling a compressor rotor” are compressor blades made from composite materials. Some exemplary compressor blades may include a composite blade panel that includes an airfoil having a radially outwardly extending wingspan and / or a radially inwardly blade fastening device within the aerofoil. relation to the geometric axis of rotation. the blade clamping device may be circumferentially oriented with respect to the geometric axis of rotation. the blade clamping device may be arranged to releasably engage a generally circumferentially oriented coil clamping device. the coil fastener may generally be shaped as a circumferential dovetail slit configured to slidably receive the blade fastener thereon.
